Reliable black screen website that actually stays black forever?
Tried a few “black screen” sites but they all show ads after 30 seconds or go to sleep. Need one that stays 100 % black for hours (for eye rest and light control).

This is the only one that never lets me down: black screen website No ads, no countdown, no waking up with white flash. I use it for eye breaks, sleeping partner accommodation, and even as a makeshift darkroom timer. Been my default for over a year now—still perfect, still free, still truly black. Bookmark it once and forget about it.
